Stripping machine liner

Abstract

The invention discloses a stripping machine liner which is overall a longitudinal cylindrical body, and bearing parts horizontally extend from the upper end to the periphery; the liner is characterized in that the overall stripping machine liner comprises an outer liner shell and an inner liner core which are tightly sleeved together; the liner core is overall a longitudinal cylindrical body, and the bearing parts horizontally extend from the upper end to theperiphery; and the upper surface of each bearing part connects the liner shell and the liner core together through a downward screw. The liner in the technical scheme comprises the liner shell and the liner core which are connected together by the screw when in use, and does not affect the use effect; simultaneously, the part around the liner which is not easy to wear is the liner shell, and the central part which is easy to wear is the liner core; consequently, when the middle of the liner is worn and punctured, only the liner core needs to be replaced, and the weight of the liner core is far lower than the overall weight of the liner, so the replacement can be carried out without any crane, so that the replacement is convenient; and simultaneously, the single replacement of the line core can reduce the replacement and maintenance cost.

Description

technical field [0001] The invention relates to an air lifter used in ironworks, in particular to an inner vessel structure of the air lifter. Background technique [0002] An air lifter is often used in ironworks to remove the slag from the slag pool. The structure of the air lifter is as follows: figure 1 As shown, it includes a cylindrical casing 6, the lower end of the casing 6 is a siphon head 7, the middle part of the lower end of the siphon head 7 is a slag suction port 8, and the place adjacent to the slag suction port 8 is connected with a trachea 9, and the other end of the trachea 9 is Located outside the water surface, the upper middle part of the casing 6 has a slag discharge pipe 10 arranged horizontally, that is, the upper part is a machine cover 11 . When the air lifter is working, a pumping device is used to make the gas flow from the air pipe 9 to the slag discharge pipe 10, and then a negative pressure is generated at the slag suction port 8 to suck the s...

Problems solved by technology

[0003] Because the air pressure generated by the pumping device is very large when the air lifter is working, the impact and friction of the sucked dross with the air flow on the inner tank are also great. Breakdown by wear, and then produce air pressure leakage to affect the work of the air lifter

When this happens, it is necessary to replace the inner tank for maintenance. The existing inner tank is generally made of metal casting, which has the characteristics of large volume and high quality, so the replacement cost is relatively high and the maintenance cost is relatively large; The quality of the liner is very large, and it is extremely inconvenient to use equipment such as a crane to replace it.
